Why kids shouldn't obey their parents?

If kids obey their parents, whatever they say, what on earth is the difference between kids and parents? I am a different person and I have my own traits which my parents have helped me grow and now they want me to change all that? 

Why should I follow someone else's ideas when I am pretty sure which direction to go? As hard as they try, they can't be our friends. They can be friendly but not friends. We don't expect our mom dad to be our friends. They are our parents, someone we look upto. They are here to protect us and to give us enough conscience to distinguish between the good and evil. Once they have done that with all they could, they should let their kids do the rest. Isn't it funny that parents teach kids to speak in the first few years and then try to teach them to shut up in the later years? If you don't follow your own paths, fall and get up again, what are you going to learn in your lives? 

Does, not obeying our parents make us bad kids? No. It makes us different from what they have thought we are but that's not a crime! All I want to trickle down to your minds is that we are at first who we are. That is our first hand identity. Only then we are sons or daughters. The secondary identity is important but not as the first one, at least not at the cost of our primary identities. I love my mom and dad .So do you. They are the best parents you can ever ask for. But we don't want them to be our job counselors, or drivers of our lives' cabs, or our managers. It is their role to teach us how to drive cabs, not to sit in the driver's seat and apply brakes and turn wherever they think is appropriate. This is our cab and once we have license to drive it, we want to enjoy the drive, the thrill of fast turns, the slow pace at traffic jams, the peek-a-boo with other drivers, to fill the petrol by ourselves, run out of it, fill it up again, race with others, and even if we somersault at roads at times, it's okay with us as long as we are alive coz these are the roads we have chosen to take. We fall but we get up. And there's pride in it than never falling by catching someone else's hands.  

I don't want to sound like a rebellious teen, neither am one. Even now that am matured enough, my mom and dad at times don't trust my instincts and it hurts. And answer to the title. We don't obey our parents all the time coz we know where we are heading for. And even though we are not too sure of it, we are sure of what we don't want. We may fail but at our own hands. And that is okay coz by now, we have already known how to rise up on ourselves. Mom and dad, I love you guys!
